Requirement for changing document type

Question

Hello Gurus,
       when I want to change sales document type, there is a requirement as following :
" When you change the sales order type for a sales document that has already been saved, both sales document types must belong to the same number range."
my question is:
   1. can sales order type be changed ?  most recommend to remove previouse sales order, and create new sales order with another sales order type.
   2. what does " the same number range" mean in the above quoted word ?
thanks very much

Answer 1

Different Order Type can share the same number range. In the case, if Sale Order Type is saved in Transaction, then it cannot be chaged.
The number range is controlled through Number Range Object, which is maintained in Sales Order Type (T.Code: VOV8).
Configuration steps are as under:
Normal Sales Order Cycle:-
Step 1: Sales Document Type
IMG > Sales and Distribution > Sales > Sales Documents >
Sales Document Header:
1. Sales Document Type:The sales document types represent the different business transactions, such as Inquiry, Quotation, Sales Order, etc. To create new sales order type, always copy as with reference to similar sales order. If possible use standard sales order.
2. Define Number Ranges For Sales Documents: Maintain number range with discussion with core team.
3. Assign Sales Area To Sales Document Types:
A. Combine sales organizations / Combine distribution channels / Combine divisions: Ensure to maintain these, else Sales Order creation will give error.
B. Assign sales order types permitted for sales areas: Assign only required Sales Order Types to required Sales Area. This will minimize selection of Sales Order Type as per sales area.
Sales Document Item:
1. Define Item Categories: If possible use Standard Item Category. Incase if required to create new, copy as from standard & maintain New.
2. Assign Item Categories: If possible, use standard. Formula for deriving item category: Sales Document Type + Item Category Group + Usage + Higher Level Item Category = Item Category
Schedule Line:
1. Define Schedule Line Categories: If possible use Standard Schedule Lines. Incase if required to create new, copy as from standard & maintain New.
2. Assign Schedule Line Categories: If possible, use standard. Formula for deriving Schedule Line: Item Category + MRP Type / No MRP Type.
Step 2:
IMG > Logistic Execution > Shipping > Deliveries >
1. Define Delivery Types: If possible use Standard Delivery Type. Incase if required to create new, copy as from standard & maintain New.
2. Define Item Categories for Deliveries: If possible use Standard Item Categories for Delivery Type. Incase if required to create new, copy as from standard & maintain New.
3. Define Number Ranges for Deliveries: Ensure to maintain number range.
Step 3:
IMG > Sales and Distribution > Billing >
1. Define Billing Types: If possible use Standard Billing Type. Incase if required to create new, copy as from standard & maintain New.
2. Define Number Range For Billing Documents: Ensure to maintain number range.
3. Maintain Copying Control For Billing Documents: Maintain relevant copy controls such as Sales Order to Billing, Deliver to Billing, etc.
Note: Ensure that Copy Control settings are done
Sales Order to Sales Order (QT --> OR): VTAA
Sales Order to Delivery (OR --> LF): VTLA
Sales Order to Billing (OR --> F1): VTFA
Delivery to Billing(LF --> F2): VTFL
Billing to Sales Order (F2 --> RE): VTAF
The configuration differs from scenario to scenario & requirement of the client.
